8 Best Battery Saver Apps for Android: Give Your Phone a Boost

Smartphones and tablets are moving ahead when it comes to raw power and performance. Unfortunately, all the features on a smartphone suck up the battery. While you can’t do anything about the actual battery capacities, you can manage how the charge is used. Many flagship smartphones ship with quad-core or even octa-core processors with large RAMs, but the batteries function on the same technology introduced years ago.

Batteries have chemical limitations which hold them back when it comes to charge timings. The only thing manufacturers can do is increase the size of the batteries. This is why we have made a list of 10 Best Battery Saver Apps for Android. While the apps won’t double or triple your battery power, they will help your device sustain a longer charge.

Note: We tested the apps on a Samsung Galaxy SIII running with a custom ROM based on Android 4.4 Kit Kat. All of the apps ran without any problems.

8. Autorun Manager

Kill the leeches

8.a Free Version

Many apps automatically start when you boot up your smartphone. These apps continuously run in the background and drain precious battery charge.

Battery saving always depends on the smartphone, the Android version and the actual capacity of the battery. These apps will help you extend the charging power of your battery. Refer to this great page about battery saving tips if you want to gain intimate knowledge about battery saving.

This list of the 10 Best Battery Saver Apps for Android is a great way to make sure your Android device makes it through the day. Try out the different apps before committing to one. Make sure you don’t have more than two of these apps running on your device at the same time. Let us know in the comments if you have any questions or additions. May the electrical force be with you.

How would someone be able to tell which of these (or any for that matter) Android apps are snooping and sending information back to a collector in the cloud?
This would be a really great thing to know.

the first place I would check is the permissions. If an app doesn’t need access to your data or contacts or something odd, but says it needs it — a flashlight app for example — that’s a good indicator.

Next, you can look at apps using a lot of data that shouldn’t.

Another option is to download an app that looks for malware or viruses. they aren’t 100% effective, but a scan might find something.

Something you need to understand, though. All apps will collect some data, even if it’s just for analytics purposes.
